Samsung Galaxy S2 (GT-i9100) – Shortcuts & Tips

Tips and stuff you won’t find in the manual, collected from the xda-developers forum, personal experimentation and other sources. Please use only tips you understand – if you don’t know what a factory reset means, you do not want to find out :)

Explanation

„Pinch“ means using 2 fingers to zoom in our out (Google this if you don’t know the word). The buttons are depicted here:

Miscellaneous hints

Factory reset (Everything will be deleted!)

Via these three ways:
  • Turn phone off, press and hold: volume Up + home + power. Use volume keys to navigate up/down, home to execute.
  • In the phone keypad: Enter *2767*3855#
  • Menu: Settings > Privacy > Factory data reset.

Codes (enter via phone keypad, the ones below work for me)
